Re: [PATCH 05/10] qemu: Wire up <memory/> live update

As advertised in one of previous commits, we want' to be able to change 'requested-size' attribute of virtio-mem on the fly. This commit does exactly that. Changing anything else is checked for and forbidden. Once guest has changed the allocation, QEMU emits an event which we will use to track the allocation. In the next commit.
